(a)on july 15,2007 , the national debt of the united states of americawas a little more than 8.8 trillion dollars. at that time, the population of the united states was a little more than 300 million. approximately how much money would each of the 300 million people living in the united states have to give the government to pay off the national debt? assume every person pays an equal amount.
(b)
a rectangular garden with dimensions five meters by six meters has a sidewalk 1 meter wide allt e way around it. what is the total area of the graden and the sidewalk?
thank you for helping if not then thank you for trying
$perperson=totalamount/numberpersons
area=(5+2)*(6+2)
(a) To find out approximately how much money each of the 300 million people would have to give to pay off the national debt, you can divide the total debt by the population.
The national debt was a little more than 8.8 trillion dollars, which is 8,800,000,000,000 dollars.
So, to find out how much money each person would have to give, divide the total debt by the population:
8,800,000,000,000 dollars / 300,000,000 people = 29,333.333 dollars per person.
Therefore, each person would have to give approximately 29,333.333 dollars to pay off the national debt if everyone paid an equal amount.
Note: This calculation assumes that the debt is evenly distributed among all individuals, which may not be the case in reality.
(b) To find the total area of the garden and the sidewalk, you need to calculate the area of both separately and then add them together.
The garden is a rectangular shape with dimensions five meters by six meters, which means its area is:
Area of the garden = length × width = 5 meters × 6 meters = 30 square meters.
The sidewalk surrounds the garden on all sides, and it has a uniform width of 1 meter. To calculate the area of the sidewalk, you need to subtract the inner rectangle's area from the total outer rectangle's area.
The outer rectangle's dimensions would be seven meters by eight meters (adding 1 meter on each side):
Area of the outer rectangle = length × width = 7 meters × 8 meters = 56 square meters.
The inner rectangle's dimensions would be the original garden dimensions minus 2 meters (1 meter on each side):
Area of the inner rectangle = (length - 2 meters) × (width - 2 meters) = 3 meters × 4 meters = 12 square meters.
Now, subtract the area of the inner rectangle from the area of the outer rectangle to find the area of the sidewalk:
Area of the sidewalk = Area of the outer rectangle - Area of the inner rectangle = 56 square meters - 12 square meters = 44 square meters.
Finally, to find the total area of the garden and the sidewalk, add the area of the garden to the area of the sidewalk:
Total area = Area of the garden + Area of the sidewalk = 30 square meters + 44 square meters = 74 square meters.
Therefore, the total area of the garden and the sidewalk is 74 square meters.
